[mythtv-users] VDPAU on Asus 8200 MB not working from HD-PVR

[Phil Linttell]

I have an Asus M3N78-VM with an HD-PVR that I run as combined BE/FE 
using VDPAU.  I'm running nVidia driver 185.18.14 and trunk (20966)  
with patches 6719, 6671, 6602, 6243.  I run with 
"EXPERIMENTALLY_ALLOW_PULSE_AUDIO=true" and ALSA over PulseAudio, output 
over the on-board HDMI.

My OS is kubuntu 9.10 alpha, with HD-PVR drivers included in my 2.6.30.9 
kernel (fixed to 720p... my STB drops of the firewire bus occasionally 
if I let the resolution float.)

I don't have problems with the video output failing to initialize.   I 
do experience some tearing and jerkiness during fast motion/panning with 
VDPAU output (720p on a 1080p display), but I get the same under mplayer 
with VDPAU.   I don't get any screen tearing or jerkiness with Normal 
profile... so it's not that the 8200 is underpowered.

I was wondering whether an upgrade to 1066MHz memory might help, as the 
motherboard uses shared video memory and I only have 800MHz.  But it 
would cost me $100 to test that one out.
